Kayser–Fleischer ring
Kayser–Fleischer rings (KF rings) are dark rings that appear to encircle the cornea of the eye. They are due to copper deposition in the Descemet's membrane as a result of particular liver diseases. They are named after German ophthalmologists Bernhard Kayser and Bruno Fleischer who first described them in 1902 and 1903. Initially thought to be due to the accumulation of silver, they were first demonstrated to contain copper in 1934.
